feed mechanism. Air cylinder 16 is used to produce a
predetermined amount of rotation of gear 13. This is
accomplished by pivotally connecting piston rod 15 to a
base of gear ‘13 at an eccentric point 193. When air
pressure is applied to cylinder 16, in a manner to be de~
scribed in connection with FIGURE 31, piston rod 15
enters the cylinder for a distance as determined by ap 10
propriate adjustment of cylinder 16 by adjustment means
Adjustable stud 204 is employed to limit the travel of
the cam follower wheel on the low side of the cam B.
This feature permits the travel of folding blade 26 to be
adjusted without the necessity of replacing or reshaping
cam B.
The direction of rotation of cam shaft 62 is counter
clockwise, as viewed in the drawings. counterclockwise
movement of cam B as shown in FIGURE 7 results in
movement of cam follower wheel 54 away from cam
shaft 62. This in turn compresses springs 57 and causes

downward direction.
The rotary motion of gear 13 is transmitted to gear
12 with which it is meshed. Gear 12 is connected to
wise direction by the downward movement of link 59 to
which it is pivotally connected. Link 65 which is pivot
ally attached to the other end of rocker arm 60 is there
by caused to move in a substantially horizontal direction.

the axle 281 of roller 10: through overrunning clutch
assembly 202. Clutch assembly 202 is so connected that
rotation of gear 12 in a direction which would tend to
feed tape into the machine, a clockwise direction as view
ed in FIGURE 3, causes a corresponding rotation of rol
ler 18. Conversely, when gear 13 is driven reversely as
a result of piston rod v15 moving out of cylinder 16 and
returning to its normal position, which, in turn, causes
Rocker arm 60 which is rotatable
about rocker arm shaft 61 is caused to rotate in a clock
to move in a counterclockwise direction about this point
by virtue of the motion of link 65 to which it is pivotally
' connected. The rotational movement of link 66 is trans
mitted to arm 28 through tension spring 67 and link 68.
Arm 28 is pivoted about point 70 as shown in FIGURE
9 and accordingly moves in a counterclockwise direction.
As shown in FIGURE 10, folding blade 26 is linked
to arm 28 by means of pin 30 and slot 29. As arm 28
moves in a counterclockwise direction about point '70,
folding blade 26 is caused to move in a downward direc
gear 12 to move in a counterclockwise direction as seen
in FIGURE 3, overrunning clutch assembly 282 causes
roller 10 to be disengaged and permits gear 12 to rotate
freely.
To prevent roller 10 from continuing to rotate in the
feeding direction after gear 13 has completed its move
tion through guide 27. Since the path of folding blade
26, and accordingly, the path of pin 38 attached thereto,
is rectilinear, slot 29 is provided to compensate for the
ment, brake assembly 194 (FIGURE 5) is employed.
Any conventional brake assembly is suitable for this pur
pose, such, as, for example, a wheel attached to axle 2011
which is provided with a spring-loaded belt appropriately
disposed to prevent overrunning of roller 10‘.
The sizes of gears 12‘ and 13, the diameter of rollers
18 and 11, and the trance of piston rod 15 are appropri
ately chosen to feed a tape strip 185 of desired length into
the machine.
Rollers 118 and 11 are grooved to prevent damage to
the Velcro tape components being fed into the machine.
As stated above, idler roller 11 is caused to rotate by
forcing it into frictional engagement with driven roller 10
fact that the end of arm 28 moves in a curved path.
Link 66, spring 67 and link 68 form the safety feature
which protects the folding blade assembly. Thus, for
example, if some circumstance precludes the downward
movement of folding blade 26, the rotation of link 66 in
a counterclockwise direction merely results in the expan
sion of tension spring 67. This safety feature thus pres
vents the positive action of cam B from being exerted by
folding blade 26 against any foreign object which may be
preventing its normal downward movement.
Clamping jaw assembly 186 is operated by means of
with set screw 184. It is necessary to groove rollers 10
and 11 to avoid excess pressure on the tape components
cam F as shown in FIGURE 12. The clamping jaw as
sembly 186 has three basic positions. At the stage of
since otherwise the pressure exerted against roller 10 by
roller 11 would distort the Velcro tape strip.
The operation of tape strip cutting assembly 18 is actu
ated by the closing of microswitch 203 which is mounted
moving toward the middle position. As cam F rotates in
on air cylinder 116 as shown in FIGURE 3. As piston rod
ing member 76 which is attached to shafts 7'7 and 78 to
15 reaches the end of its travel into cylinder 16, adjust~

in a downward direction and causes rocker arm 80 which
operation depicted in FIGURE 12, the clamping jaw is
a counterclockwise direction, cam follower wheel 73
moves downward away from cam shaft 62 thereby caus
able member 204 mounted on piston rod 15 contacts mi
croswitch 203 and causes it to close. Referring to FIG
URE 4, the closing of microswitch 203 results in a down

tion about rocker arm shaft 61. This movement of rocker
ward movement of piston rod 20, thereby causing the
Velcro tape strip to be cut. As indicated in FIGURE 4,
the air cylinder 19 is pivoted about point 138 to permit
the end of piston rod 28‘ to follow the cured path of knife
edge holder 22 as the latter rotates about point 24. FIG
arm 80 causes link 81 to move to the left. This movement
60
in turn is transmitted through links 82., 83 and 88 to link
91. The movement to the left of link 91, which is pivot
ally connected to link 89, causes movable jaw 32 to rotate
about pivot point 92 and thus move toward stationary jaw
URE 7 shows Velcro ta-pe strip 185 just after it has been
cut.
To assure the proper orientation of each Velcro tape
as it is fed into the machine prior to the cutting step,
guides 69, 71 and 72 are provided.
The action of a folding blade 26 is controlled by the
rotation of cam B as shown in FIGURE 7. Cam follower
assembly 55 is employed to produce the appropriate recti
linear motion based on the design of cam B. As shown
in FIGURE 7, yoke 56 is mounted on cam shaft 62 in
a manner which permits shaft 62 to rotate‘ independently
thereof. Cam follower wheel 54 is connected to member
58 through guides 63 and 64 which pass through holes
When cam F, as shown in FIGURE 12, is rotated so
that the follower wheel 73 is riding on the highest point
of the cam, jaws 32 and 31 assume the locked position.
This situation is depicted in FIGURES 8 and 11. When
the jaws are in the locked position, serrated edge 35,
which is attached to the lower of pins 34 pinches the
folded Velcro tape. This serrated edge is used to prevent
upward movement of the folded tape which might other
wise occur as folding blade 26 moves upward out of
contact with the folded Velcro strip 185.
A safety feature is included in the operation of clamp
ing jaw assembly 186. As shown in FIGURE 12, link
